Regarding rr client configuration

Hi, I am new to bird and trying to configure route reflector client in my bgp configuration. Just curious if the below configuration is correct? i am running ebgp between the switch and traffic generator and i see that the bgp routes are getting installed in my switch. The local AS is 20 and remote AS is 10. Running another software on the switch which is listening for these BGP routes (ibgp) on port 1179 and ip 127.0.0.1 which is loopback interface. My configuration is given below. The iBGP session are getting established and it is also not consistent. I have to restart bird multiple times to get it to establish the connection. Secondly I saw some template configuration for rr in the bird and used that too. Not sure if it is required? if so is there any changes required in the configuration below. Lastly is the cluster id configs required? protocol bgp bgp_20 { description "My IBGP"; local as 20; neighbor 127.0.0.1 port 1179 as 20; # multihop; hold time 90; startup hold time 90; connect retry time 30; keepalive time 30; # defaults to hold time / 3 connect delay time 5; # How long do we wait before initial connect next hop self; # Disable next hop processing and always advertii ise our local address as nexthop path metric 1; # Prefer routes with shorter paths (like Cisco dd does) default bgp_med 0; # MED value we use for comparison when none is dd defined rr client; # I am a route reflector and the neighor is my ccc lient rr cluster id 1.0.0.1; # Use this value for cluster id instead of my rooo uter id import all; export all; } # Template usage example template bgp rr_client { router id 3.3.3.3; local as 10; multihop; rr client; rr cluster id 1.0.0.1; } # protocol bgp rr_ibgp from rr_client { neighbor 127.0.0.1 as 40; }

import OSPF external routes

Hello bird users, I ran into the issue with importing OSPF external route. Maybe someone can point me in the right direction. This is the OSPF filter: filter OSPF_IN { if source = RTS_OSPF then accept; # reject; accept; } And this is a route in question - a loopback interface of another router/OSPF neighbor: bird> show route for 10.120.0.55 all 10.120.0.55/32 via x.x.x.x on bond1 [EDGE_OSPF 19:49:20] * E1 (150/10) [10.2.55.2] Type: OSPF-E1 unicast univ OSPF.metric1: 10 OSPF.metric2: 16777215 OSPF.tag: 0x00000000 OSPF.router_id: 10.2.55.2 bird> bird> show ospf state router 10.2.55.1 distance 10 ...[some output is omitted ] external 10.120.0.55/32 metric 0 When I replace 'accept' with 'reject' in the filter, I'm not able to see 10.120.0.55/32 route in the FIB. Thanks, Roman.

routing using kernel fibs
by Angel 04 Jun '16

Hello, We are configuring a BSDRP server (FreeBSD router.bsdrp.net 10.3-RELEASE-p2 FreeBSD 10.3-RELEASE-p2 #0 r299108M). We have two fullrouting bgp carriers, some bgp members and some ospf members. To isolate OSPF members we want to use kernel fibs. But we do not understand how it works. What we need is a diferent table for each ospf member, so for example ospf1member will use carrier1 routes, and ospf2member will use carrier2 routes. Which is the best way to get this? If we configure kernel fib 1 with carrier1 routes, but ospf1 doesn't use it, how we can to configure because ospf1 use kernel fib 1? How to do the same for ospf2 with kernel fib 2? We have to configure interfaces in these fibs? What about carriers interface? Could you give us some example to get above configuration? Regards, Angel.

Hi guys, Using Bird 1.5.0 Is is somehow possible to have an empty list? define AllowedExportAsList = []; This gives me a syntax error. Greetings, Stefan
